The common houseplant is Dracaena fragrans, the corn plant. Janet Craig, Warneckii, and Massangeana stay on this URL. NCSU: it is often confused with Dracaena sanderiana (lucky bamboo). That is a different plant. Snake plant is Dracaena trifasciata, at how to propagate a snake plant.
NCSU’s recommended strategy is stem cutting. Iowa also lists corn plant for cane sections and for air layering. Illinois marks stem and air layering. Missouri: stem sections are relatively slow, and air layering is on the table.
For mix in a drained pot, see soil propagation. Air layering how-to lives on air layering.
Stem cuttings
NCSU: propagate by stem cuttings.
Iowa’s stem-tip houseplant page lists Dracaena fragrans (corn plant) with that list’s general recipe: 3 to 6 inches, at least two nodes, lower leaves off, hormone optional, at least one node in the media. Most houseplant stem cuttings on that page form roots in 3 to 6 weeks. Those numbers are the list page.
Illinois lists Dracaena under stem cuttings. Their general stem recipe is 3 to 6 inches, two to six nodes.
Missouri lists a herbaceous cutting for dracaena.
Cane cuttings
Iowa: cane cuttings work well for Dracaena. Corn plant is on that list. Cut the leafless cane into 2- to 3-inch segments, each with at least two nodes. Hormone optional. Lay them horizontally in perlite, coarse sand, or vermiculite, just at the surface. Bright, indirect light and high humidity. On that page, new roots and shoots in 8 to 10 weeks. Pot when they are about 1 inch long.
NCSU: leafless sections 2 to 3 inches, one or two nodes. Horizontal, or vertical with about half in the mix and a bud facing up. Corn plant is the named example. Pot when roots and new shoots appear.
Illinois: two- or three-inch cane, at least two nodes. Vertical (new leaves at exposed nodes, roots at buried ones) or horizontal (half buried).
Arkansas Extension: cane from 2 inches to many feet. For the most plants, 2-inch pieces with at least one node, on their side, half buried. Longer dracaena pieces can go in vertically, base in the mix; a shoot grows from the top bud.
Iowa wants at least two nodes. NCSU allows one or two. Arkansas names one. Keep the names. Do not average 8 to 10 weeks (Iowa cane page) with anything else.
Air layering
Iowa lists Dracaena fragrans for air layering, not simple layering. For monocots such as dracaena: a point 12 to 18 inches from the tip, an upward-slanting cut about one-third of the way through the stem, a toothpick to hold it open, hormone, moist unmilled sphagnum, plastic. Roots in several weeks; some species several months. Cut below the wrap when roots are several inches long.
NCSU names Dracaena fragrans ‘Massangeana’ (corn plant) for the same monocot cut, about 1 foot from the tip, one-third of the way through.
Arkansas: on dracaena, a diagonal slice halfway through, held open with a stick. Roots usually after two to four months.
Illinois marks air layering for Dracaena. Missouri does too.
One-third of the way through (Iowa, NCSU) and halfway (Arkansas) are not the same cut. Several weeks to several months (Iowa), two to four months (Arkansas) are not one number.
Common mistakes
- Treating lucky bamboo as this page. NCSU: corn plant is often confused with Dracaena sanderiana.
- A cane with no node. Iowa: at least two. NCSU: one or two.
- Averaging Iowa’s 8 to 10 weeks on cane with Iowa’s 3 to 6 weeks on stem tips.
- A dicot bark ring on a corn plant. Iowa and NCSU: dracaena is the slanting monocot cut, not the rubber-tree girdle.
People also ask
Tip, cane, or air layer?
NCSU’s strategy is stem cutting. Iowa also lists cane and air layering for corn plant. A leafy tip is a stem cutting. A bald trunk is a cane. A tall plant you do not want to cut free yet is an air layer.
How long?
Iowa stem-tip list: 3 to 6 weeks for most houseplants on that page. Iowa cane page: 8 to 10 weeks. Iowa air layering: several weeks, some species several months. Arkansas air layer: two to four months. Those are not one number.
Is corn plant a snake plant?
No. Snake plant is Dracaena trifasciata, at how to propagate a snake plant.
